Finally installing my Header(s), Highflow cat, 3" exhaust and my injen CAI tomorrow.

WITHOUT a tune
From stock, installing these mods, a buddy of mine asked my what kind of gains I will see in terms of #'s

What is a good estimate to give him? I was thinking about 10 hp and 8-12 tq


Thanks

 

like 2hp, how is he going to gain any power if he can't be tuned for the new flow? Maybe the numbers you suggested AFTER a tune.

 

only 2?

 

Well, I'm not a dyno so how the hell would I know? My point was you're not going to see much for gains outside of what the existing tune is capable of, the engineers when they built the car used the proper intake and exhaust parts for that cars tune.

But hey, there's a bunch of people on this forum that are smarter than engineers who build cars and will tell you otherwise so take what you want from it.

 

just because its a quick question doesnt mean it goes in general. moved

 

I seem to never put threads in the right area..
